Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Bestimmung der Position (P) eine Körpers (1) mit einem Feinmeßsystem (20) und einem Grobmeßsystem (30). Der Code (32) des Grobmeßsystems (30) wird vom Feinmeßsystem (20) gesteuert ausgelesen. Das Grobmeßsystem (30) enthält eine Grobcodescheibe (31), die vom Feinmeßsystem (20) über ein Untersetzungsgetriebe (40) angetrieben wird. Das Untersetzungsverhältnis 1/U des Untersetzungsgetriebes (40) ist annähernd 1:1. Die Grobcodescheibe (31) weist hintereinander angeordnete Sektoren mit Codewerten (C) auf, welche die absolute Grobposition des Körpers (1) angeben. Gemäß der Erfindung werden nicht aufeinanderfolgende Sektoren der Grobcodescheibe (31) ausgelesen.
